VALVE.

Application filed May 17,

Bel it known that I, Hnnnr D. HILDE- innxNn, .residing at Mount Vernon', in the county ot Knox and State oi Ohio, a citizen ot the United States,lhave invented or discovered certain new and useful Improvements in '"ialves'ot' which improvements `the 4following is specification.- i

'ln Lettersfiatent No. 1,229,456, granted June 12, 19t?, descrilicd and shown a construction ot` valve mechanism having in combination oppositely disposed valve seats having ports therethrough and valves consisting ot resilient metal strips which were so supported by abutments in operative relation to the ports that the strips could be bent or :tlexed` by the pressure of fluid to permit of escape ot' fluid through the ports. In one ot the constructions shown in said patent, the supporting abutments were arranged adjacent to the ends of the strip and the openingiiexure of the spring was intermediate suchl abutments. In another torni the supporting abutment is arranged to bear against they strips at points approximately midway their lengths `so that the opening ot' the valve is due to the iieXure of the strip on opposite sides of the abutinents.

The invention described and claimed herein has for its objecta construction oi valve mechanism, in which the valves are maintained in normal or closed position by a suitably constructed and arranged resilient means, and the opening of the port is effected by substantially equal movement 01"' the strip `for its entire lengthr against such pressure or by such equal movement and more or less tlexure ot the strip forming the valve. The invention is hereinafter more fully described and claimed.

ln the accompanying drawingforn'iing a part of this specification, Fig. 1 is a top plan view showing the improvement embodied in a valve `mechanism tor an air or gas coinpressoi; Fig. 2 and Fig. 3 are sectional views on planes indicated respectively7 b v the lines 11E-II and Hllll, Fig. l; Figs.` et, 5, 6, 7 and 8 are diagrammatic views ot different arrangements and constructions oi.z springs. i

in the practice oiE the invention, the metal; strips l and their controlling spring or springs 2 are arranged in grooves 3 in the block et which may be of any peripheral contour,'and the grooves may be yparallel as vrigidity relative to the strips may be resilient 1920. Serial No. 381,908.

shown herein or radial as shown in the patent herein before mentioned. i The ribs 5 intermediate of the grooves are made hollow tor the flow of gas, air or other iiows `to the ports 6 formed in the side walls ot the ribs as shown in Fig. 3. l l

`'lhe valves consist not metal strips which lare yieldingly heldin their respective seats by meansof a spring 2 which may be semieliptical .in shape or of any otherfdesired shape or construction.. `Ars shown,r the spring or springs are arranged intermediate thevalves and bear upon both valves. As

for exam le in the construction shown inV Figs. l, 2, and 3, the ends oi the spring :bear

on one valve or strip at vpoints kadjacent to on the opposite strip at a point The stripv of metal be made with such a spring that the entire movements of the valves are due to a yielding of the spring, or if-desirechthe and suiiiciently yieldingthat the opening of the port is due in part to the flexure ot' the strip itself.

In .lieu .oi' a single Figs. l, 2, and 3, two springs may be interposed between the valve strips as shown in Figs. 4, 5, 6, 7 and 8.

In the construction shown in Fig. i `the springs are arranged to bear at `their ends in the strips and against one another at a point intermediate the ends while Fig. 8 shows a reversed arrangement ot the springs, the springs being in contact with the valve at points intermediate their while the latter are in contact. In the conits ends and intermediate' its ends. forming the valves may struction shown in Fig. 6, two springs are' spring as shown in` ends,

employed, each bearing at their ends on one strip or valve, and at an intermediate point on the opposite strip or valve.

In lieu oi ellipticalsprings other shapes or constructions ot springs may be einployed without departing` troni the spirit oi" the invention described and claimed herein'. die :tor example, two substz'lntiall'v U-shaped springs as 2' `may be so arranged intermediate the valves that their ends will bear on the respective valves, as shown in Fig. 5. In order to prevent the being tipped .from operative positions, they are forced with eyes rz engaging pins 8 projecting from the bottoms ot the grooves As shown in Fig. 7, spiral springs 2b may be employe-d. The eyes of the spiral are springs 2"' slipped onto pins 9 in the bottoms .of the grooves 3, while the outer members or coils of the spiral have dianletrieally opposite points in contact with the respective valve strips. i. I

It is characteristic of the construction shown herein that the resilient means interposed between the valve strips is operative on both valves. This` characteristic is found in the form shown in Fig. i and Fig. S, for although neither springis in direct engagement with both valves, the springs ha-vetheir ends .or points intermediate the ends in Contact so that each valve is controlled by both springs.

I claim herein as my invention: 1.,A valve mechanism for pumps, etc., having in combination two ,oppositely disposed valve seats having ports therethrough, flat strips of suitable material for closing the ports, both side edges of said strips being free to move substantially equal distanees from the seats and a spring 'tor yieldingly holding said strips against the valve seats.

2. Av valve mechanism'for pumps, etc., having in combination two oppositely disposed valve seats having ports therethrough, metal strips for closing said, ports, the side edges oi' said strips being free to move substantially equal distances :trom the seats and resilient means interposed between the valve strips for yieldingly holding said valves against the seats. i

3. A valve mechanism for pumps, etc.. having in combination two oppositely disposed valve seats having ports therethrough, metal valve strips for closing said ports, both side edges of said strips being free to move substantially equal distances from the seats and a spring adapted to bear against both strips for yieldingly holding the same against the respective seats.

il.. A valve mechanism orpumps, etc., having in combination two oppositely disposed valve seats having ports therethrough, resiliently flexible metal strips for, closing said ports and resilient means'interposed between the strips for holding themagainst the seats. v

In testimony whereof, I have hereunto set my hand.
